Be it known that I, WALTER. DRIT'TOX, of Abingdon, in the county of Knox', and State of'llinois, have invented. a new and improved D'eviee for. Cutting-Bolts and Rivets; and I do herebyr declare that the' following' is a full, clear, :ind exnct description thereof, which vwill enable these 'skilled in the art to malte and use the same, reference being hhd to the accompanying dra-wings,'forming part of this specification. I

This invention relates to u new and improved device for slitting bolts end'rivetso,nd consists in a peculiar construction of parts, a's hereinafter shown and described, whereby e very simple, portable, and eiiicientv device is obtained for the purpose. In the uccompnnying'sheet of drawingsi Figure 1 is a side view of my invention.

Figure 2 is en edge `v 'iew oi'y the seme. I 4 Y lFigure 3, n section of tiresome, teken in the linea: fr, fig. 1.

Similar letters of 4reference indicate corresponding parts.

A/represents a'metel guide, which is composed of a metalfbar, bent in 1-form, and linvihg two pareille? sides a a. Within this guide there ure fitted two curved bers B B', .which are connected by :t pivot-bolt b at one end, und have cutters, t' e, ttt their' opposite ends, the cutters lapping'over the edges of vthe guide A; und each' bar has n' pin, d, passing throughit at the inner redges of the guide, the pin 'of the bar B fitting in notches, e,

in the inner edges of the guide, asshown in lig. l. In'the operi end of the guide A there are fitted two l'evers,

D D, both being secured by one and the same pivot-boit,f, thelatter passing through the levers et such a point vthat un eccentric, g, will be nt the endrof each lever, said ends being rounded or made' inI seniicirculur'form, as

plainly shown in gn 1. Between the two bars B B there is placed a spring, which has a tendency to keep the cutters c cnpnrt, the ends of the spring 'bearing against the bers at their junction with the cutters.

Freni-tbe above description it will be seen that, by forcing apart the levers DD, as shawl-iin g. 1', the

cutters c c will be spread apart under the iniuence of the spring E, and the implement is then aidjusted toits work, so that the bolt or rivet to. be cut (shown in red in iig. 1) .wi1l be` between the cutters, andthe two'levers ureithen pressed towards each other, the eccentrics g g acting against the ber B, endlcnusing the euttersie to sever thebolt. By this .arrangement of parts a very lpowerful'leverage is obtained, as welles a very simple end'.

portable device. l

I claim as new, and' desire te secure b y Letters Pa-tent. t The guide A, bersy B B', connected by ,e pivot-holt, b, at one end, and provided with cutters, c 'at'the oppositefend, andthe levers D D., provided with e in the manner as and for the purpose set forth.
